zen of the United States, residing at St. Paul, I

in the county of'Ramsey and State ofMinnesota, have invented certainnewand useful Improvements in Manure Gatherers and Loaders; and Idodeclare the following to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification. j

My invention relates to manure gatherers and loaders, and particularlyto the class wherein a fork or'shov'el device is provided and operatedby a suitable hoisting apparatus.

The primary object of the invention is to provide various improvementsover the constructions describedin Letters Patents of the United Statesgranted to me'September 13, 1898, No. 610,609, and November 12, 1901,No. 686,532.

The various improvements will be clearly pointed out in the belowdescription and claims, reference being had to the'accompanyingdrawings, in which- Figure 1 is a perspective view of the completeapparatus as when in use. Fig. 2 is a top view of the shovel and aportion of its handle. Fig. 3 is a side view of the parts shown in Fig.2 with a piece partly broken away between and c. Fig. 4 is a top view ofthe rear portion of the handle. Fig. 5 is aside view of the part shownin Fig. 4. Fig; 6 is a cross-section on the line a a, of Fig. 2 lookingfrom right to left. Fig. 7 is a crosssection on the line b b of Fig. 2.Fig. 8 is a side View of the lower end of the mast of the hoistingdevice. Fig. 0 is a top View of the plate supporting the mast, and Fig.10 is a front view of the top of the mast. Fig. 11 is an enlarged's'ide'View of' the main parts to the left in Fig. 3 with the shell 16 in see-Fig. 12'is 'a top viewof the parts shown in Fig. 11. Fig. 13is anenlarged side View,

and Fig. 14 a rear view, of the clamping-clip 57. Fig. 15 is an enlargedtop view of one of the anchoring-pegs with the clamp and a fraction ofthe frame-timber secured thereby.

Referring to the drawings by referenceto the front end is a side handle3, which is sometimes useful in controlling the fork. Near said handle 3are secured to the beam 1 the diagonally and forwardlyextending arms 4,forming a frame in Whose front ends are journaled the trunnions 5,projecting from the fork proper, which tilts on said trunnions, andconsists of a series of tines 6, connected together at their upturnedrear ends by the bar 7 and'strengthened by two crossrods 8 and 9, eachof which is encircled between the tines by pieces of tubinglO, formingsupports between the tines when. a nut at the end ofeach rod draws thetines firmly together to make the fork rigid. Upon two of said tubingsrevolve two rollers 11, which serve as supporting-wheels for the forkupon the ground.

12 represents cheek-pieces secured to so as to strengthen the curvedrear portion of the fork and to guard to some extent the load fromfalling out at the sides.

13 represents guides secured at the sides of the fork near its cornersfor the arms 4 toprevent side strain on the toothed sector 14 at therear of-the fork, which is guided between the side lips 15 of the frontend of the beam 1 and is engaged by two sliding catches l6 and 17,having each a rod with a coil-spring 16 and 17 respectively, tending tohold the catches normally engaged with the teeth of the sector. Thecatch 16 is of the common sliding form. It slides in a shell 18, whichprotects the spring against dirt and damage from contact. From the rearend 19 of this catch extends the wire or light rod 20 to the short arm21 of a lever 21 23, fulcrumed at 22 near the rear end of the beam 1 andhaving its long arm 23 serving as a handle. 'When this handle is broughtclose to the'beannit becomes spring-held against the latter by theaction of the spring 16 pulling on the-arm 21, which approaches the beamin advance of the long arm 23, and thus get inward past the fulcrum 22,so that the latch 16 may at any time be locked in a disengaged positionfrom the sector 14. The upper catch 17 is pivotally placed on a clevis24, pivoted at 25 to the beam. ,The front end of this catch is beveled,so that it will play downward over the teetlncausing the spring 17 toyield and take hold of the teeth only. when impelled upward. Ina notchin the rear end of the catch 17 is attached to the clevis 24 a rod 26,which passes through the spring l7 ,is guided at .27, and by the wire orrod 26 connected to the short arm 21 of the lever 21 23 fulcrumed at 22at the opposite side of the beam from the lever 21 23. The function ofthe two opposite levers is similar and is already described about latch16.

The frame-arms 4 are strongly secured to the beam not only by the bolts28, but also by the rods 29 and 30 with tubes 29 and 30 interposedthereon between the beam and the arms 4 and the upper braces 31 and 32,one on each of them, and the brace at the bottom of one of them.

34 is a bridge supporting the brace 32 over the rod 26 while the lowerbrace 32 bears against the shell 13, and the brace 31 is supported onthe grooved head of a tensionscrew 35, placed in the clevis 36, bridgingover the sliding rod 26 The trunnions 5 are secured on the cheekpieces12 slightly above the rod 8, so that the fork has a tendency to tiltforward when the bail 37, pivoted on the trunnions, pulls forwardly, asshown to the right in. Fig. 1.

38 is a bracing-plate secured across the front junction of the bail tostiffen it and to create an eye 39 for the hook 40 of the hoistingdevice forming a portion of the apparatus and which will now bedescribed.

\Vhile the hoisting-machine may be of various forms and arrangements, asindicated in my former patents above referred to, I prefer the portablehoisting device illustrated in Fig. 1 and comprising two horizontal basetimbers or bars 41, secured together at one end by the step-plate 42 andheld at about right angle to each other by the horizontal brace 43. Inthe step 44 (best shown in Fig. 5)).1 place the journal 45, formed on acasting 46, on which the lower end of the mast 47 is secured. Thissocket-shaped casting 46 is formed with a projection 48, to which ispivoted the lower end of the boom 49 and opposite thereof with aprojection 50, between which and the eyebolt 51, secured in the mast, ispivoted to swing horizontally the sheave-hood 52, having the sheave 53.The mast is held in its upright position by the diagonal braces 54,which have their upper ends provided with journal-plates 55 for the topjournal 56 of the mast and their lower ends secured by the clips 57 tothe base-timbers 41, so that by loosening the nuts 58 of the clips thebase-timbers may be adjusted to possible inclines of the ground withoutthrowing the mast out of its plumb position. The adjust-ability alsoenables the mast to be sufficiently leaned toward the wagon or otherdepositing place, so as to give the fork and boom a tendency to approachthat place when raised with the load on it.

To the lower ends of each of the timbers 54 are pivoted loosely the endsof a U-shaped clamp or strap 60, adapted to embrace the posts oranchoring-pins 61, driven in the ground and to be clamped thereon bydrawing tight the nut 62 at the end of the pivotbolt, since the timber54 is smaller than the post 61.

63 represents an auxiliary post, over which and the post 61 a rope orchain 64 may be tied as a further safeguard against accidental looseningof the hoisting-frame from the ground-posts.

The boom 49 is adjustably held in the desired inclined position by thecable 65, extending from the top of the boom overa sheave 65 on the pin66 in the top of the mast and downward and adjustably secured on a cleat67 on the mast. Another cable 68 is secured with one end at 69 to theboom, is passed thence over the sheave in the hook-block 70, thence overa sheave 71 in the top of the boom, thence over a sheave 72 in thetop ofthe mast, thence downward and over the sheave 53, from which it passesto any'snitable source of power, which in the present drawing isindicated by a horse 73.

In Figs. 8 and 9 is shown that the plate 42 and casting 46 are bothprovided with integral wearing-collars 74 75, so that the castingsproper will not come together and cause undue friction even after muchwear.

The two outer tines of the fork have their upwardly-turned rear endsformed into projecting points or horns 76, adapt-ed to take hold in theground or of other objects and turn the fork on its trunnions if itshould happen to get on a dead-center with its bottom up. \Vhen not onsuch dead-center its normal tendency is to hang on the trunnions withthe toothed sector toward the catches 16 and 17.

In further describing theoperation of the device it will be understoodthat the apparatus is used for raking together and depositing in a wagonor in heaps manure and other substances by swinging the boom 49 in anydesired direction and pulling the fork on its wheels or rollers 11 tothe various parts of the ground upon a large area, and whenever the forkgets full or loaded the animal 73 (or other power) draws it under theouter end of the boom and raises it high enough to empty the load upon awagon or other place of deposit, over which it is easily swung by theoperator 77, especially if the mast inclines some toward that place. Inemptying the fork the operator usually simply pulls the lever 23 so asto unlock the catch 16 and the load will tilt the fork forward and emptyit; but if the load happens to be evenly balanced or even heaviest backof the trunnions 5, then the lever 23 is thrown closeto the beam 1,where it is spring-held, as described, and the operator gives an upwardjerk with the beam 1. This causes the rear part of the fork and load,now supported only by the catch 17, to

ICS

flap said catch upwardly and tilt forwardly and unload. When the largestpossible portion of the ground'has thus been operated on, theanchoring-pins are released and removed to the next portion of theground to be operated on, and to that place the hoist ing device ispulled by hitching the horse to it near the base of the mast, thebase-timbers 41 serving as runners, or if the ground is uneven one ofsaid timbers may be raised partly from the ground and supported by awalking person during the short drive.
